這兩個可數名詞雖然都是指「費用」，但它們的含意其實截然不同。Fee 通常是指專業服務或諮詢所索取的費用，如 lawyer’s fees (律師費)、doctor’s fees (醫師費) 或 counseling fees (諮詢費)。請看下面的例句：
- International school fees have risen by 5% this year. (今年國際的學費已上揚 5%)
- I have to pay the solicitor’s fees for helping me make a will. (我須支付律師協助我立遺囑所需的費用)
- What are the fees for a weekly house cleaning service? (每週的房子打掃服務費是多少呢？)
